macroFMARK

#define FMARK 0x00001000

mark during gc(), same value as O_RESOLVE_BENEATH

macroFDEFER

#define FDEFER 0x00002000

defer for next gc pass, same value as O_UNIQUE

macroFWASLOCKED

#define FWASLOCKED 0x00004000

has or has had an advisory fcntl lock

macroFHASLOCK

#define FHASLOCK FWASLOCKED

obsolete compatibility name

macroFWASWRITTEN

#define FWASWRITTEN 0x00010000

descriptor was written

macroFNOCACHE

#define FNOCACHE 0x00040000

fcntl(F_NOCACHE, 1)

macroFNORDAHEAD

#define FNORDAHEAD 0x00080000

fcntl(F_RDAHEAD, 0)

macroFNODIRECT

#define FNODIRECT 0x00800000

fcntl(F_NODIRECT, 1)

macroFENCRYPTED

#define FENCRYPTED 0x02000000

macroFSINGLE_WRITER

fcntl(F_SINGLE_WRITER, 1)

macroO_CLOFORK

#define O_CLOFORK 0x08000000

implicitly set FD_CLOFORK

macroFUNENCRYPTED

#define FUNENCRYPTED 0x10000000

macroFEXEC

#define FEXEC O_EXEC

macroFSEARCH

#define FSEARCH FEXEC

macroFFLAGS

convert from open() flags to/from fflags; convert O_RD/WR to FREAD/FWRITE O_EXEC turns off FREAD/FWRITE

#define FFLAGS(oflags) (((oflags) & O_EXEC) ? ((oflags) & ~(O_ACCMODE)) : ((oflags) + 1))

macroOFLAGS

There is no way to convey a lack of O_RDONLY but the presence of O_EXEC means that

#define OFLAGS(fflags) (((fflags) & FEXEC) ? ((fflags) & ~(O_ACCMODE)) : ((fflags) - 1))

macroFMASK

bits to save after open

#define FMASK (FREAD|FWRITE|FAPPEND|FASYNC|FFSYNC|FFDSYNC|FNONBLOCK|FEXEC)

macroFCNTLFLAGS

bits settable by fcntl(F_SETFL, ...)

#define FCNTLFLAGS (FAPPEND|FASYNC|FFSYNC|FFDSYNC|FNONBLOCK)

#define F_WAIT 0x010

Wait until lock is granted

macroF_FLOCK

#define F_FLOCK 0x020

Use flock(2) semantics for lock

macroF_POSIX

#define F_POSIX 0x040

Use POSIX semantics for lock

macroF_PROV

#define F_PROV 0x080

Non-coalesced provisional lock

macroF_WAKE1_SAFE

#define F_WAKE1_SAFE 0x100

its safe to only wake one waiter

macroF_ABORT

#define F_ABORT 0x200
